Next in the row is the installation of the ruby gems package.
So it should be easy… just following the instructions.
So…..
root@sunny:~# wget http://rubyforge.org/frs/download.php/38647/rubygems-1.2.0.zip
root@sunny:~# unzip rubygems-1.2.0.zip
root@sunny:~# cd rubygems-1.2.0
root@sunny:~# ruby setup.rb config
./lib/rubygems/spec_fetcher.rb:1:in `require’: no such file to load — zlib (LoadError)
from ./lib/rubygems/spec_fetcher.rb:1
from ./lib/rubygems/source_index.rb:10:in `require’
from ./lib/rubygems/source_index.rb:10
from ./lib/rubygems.rb:767:in `require’
from ./lib/rubygems.rb:767
from setup.rb:22:in `require’
from setup.rb:22
Welcom to error world ;-).
Okay…. should be easy to solve:
root@sunny:~# apt-get install libzlib-ruby zlib1g-dev
or for 64bit Plattforms:
root@sunny:~# apt-get install libzlib-ruby lib64z1-dev
But still the same Error!
Finally i found something in the Weblog of Lucas Chan.
Hm its about readhat/centos…. okay why not.
Just go to the ruby sources:
root@sunny:~# cd /usr/local/src/ruby-1.8.6-p110/
root@sunny:~# cd ext/zlib
root@sunny:~# ruby ruby extconf.rb –with-zlib-include=/usr/include –with-zlib-lib=/usr/lib
checking for deflateReset() in -lz… yes
checking for zlib.h… yes
checking for kind of operating system… Unix
creating Makefile
root@sunny:~# make
root@sunny:~# make install
and finally:
root@sunny:~# cd /usr/local/src/rubygems-1.2.0/
root@sunny:~# ruby setup.rb config
….
== Thanks
Keep those gems coming!

Again: something learned!
Thanks for posting that. I found your site when I googled for the error. I had the same issue.
can you tell me exactly what your command did?
root@sunny:~# ruby extconf.rb ruby extconf.rb –with-zlib-include=/usr/include –with-zlib-lib=/usr/lib
thanks
Mark
Hello Mark,
there was an error:
the line should be:
root@sunny:~# ruby ruby extconf.rb –with-zlib-include=/usr/include –with-zlib-lib=/usr/lib
It just sets the lib and header path for the zlib extension.
Normally if you use apt-get you should already have this extension delivered with your ruby package. In my case, i compiled Ruby myself. The gem installer uses the zlib extension so i had to compile this extension manually.
Wow, thanks, it helped!
Thanks a lot for this post, it definitely helped.
OMG, thank you so much! I was getting crazy about this zlib stuff!
